構成されている。
The structure of the opening/closing door in conventional heating cooking equipment is as follows:
Regardless of whether the door is a side-opening type or a top- or bottom-opening type, a door cover is attached to the back of the frame-shaped door body (door plate), and a stepped door cover is attached to the front inner edge of the door body. A concave portion is formed, an outer barrier made of heat-resistant glass is placed in the concave portion, and a frame-shaped decorative frame (door sash) is attached to the front side of the door body with this outer barrier installed using a large number of set screws. Configured for fixed assembly.
しかしながら、上述した加熱調理装置における

However, in the structure of the opening/closing door in the heating cooking device described above, since the decorative frame is molded from a synthetic resin material, the door has to be molded in advance to form a collar portion into which a plurality of set screws are screwed. In the vicinity of the flange of the main body, the cooling temperature during cooling varies due to the relationship with the wall thickness, resulting in streak-like "sink marks".
Not only is there a risk of damaging the external shape of the door body, but the decorative frame itself may deform and swell due to the weight of the outer barrier made of heat-resistant glass and the thermal effects during cooking. Due to this, there is a possibility that a gap may be created at the joint surface of the decorative frame, resulting in leakage of radio waves.
又一方、開閉扉全体を止ねじで固定する関係
上、止ねじや工具を必要とし、組立が面倒であ
り、量産による省力化を図ることが困難である。 On the other hand, since the entire opening/closing door is fixed with set screws, set screws and tools are required, and assembly is troublesome, making it difficult to achieve labor savings through mass production.
本考案は、上述した事情に鑑みてなされたもの
